Yes, 1kV DC is scary.

Exciting news Andrea !!

With regards to the I2S receiver, it seems to be HDMI right ?

I am definitely in for the DAC and the FIFO

Yes, the I2S receiver is over HDMI, it's the TWSAFB-RX.
The transmitter is the TWSAFB-TX.

Andrea. Do you think that HDMI interface for I2S is optimal?

HDMI is before the fifo+isolator, it shouldn't make any difference.

I think the source is not much important, the FIFO should isolate the DAC from the source since they work in different time domains.

Yes, the jitter coming from the source cannot affect the DAC because the FIFO isolates them.
Data incoming from the source are stored in a memory and then they coming out with a different master clock, the FIFO is asynchronous.

The quality of the output depends on the quality of the FIFO master clock.
